Is there a drawing of turntable assembly inside the furnace?

The field components drawings don’t show anything for the inside of the bottom of the furnace. You know, the turntable piece and side for sending the balls to the collector. We noticed on the field that there is a gap between that circular assembly and the furnace wall. We want to mock up the bottom of the furnace and include a mock up of this assembly.

Not quite sure where an assembly is for that. Have you checked the SW field and Inventor field?
Here are some pictures of the turntable setup with the gap, if that’s of any help.

The furnace is actually called a boiler. I am leaving this note so that anyone that searches CD for boiler might find this thread.
